Hi,

For last few days I’m testing what causes battery drain faster. My phone is on Airplane mode, with only watch face… using as a “watch” only device. Also pedometer is ON.

Here is my first result.

Firmware: DM20_LEM10_V1.1_20200711
Battery saver mode: OFF

What I noticed is that the screen uses a lot of power. I currently have BT on, WiFi on, GPS on, Gesture off, 4G off, Battery saving on below 15%, all processes killed except messenger and Whatsapp.
I only use 4G on demand.

I get currently about 38 hours of usage.

I’ve the same settings… I only use 3G but for a few days… i’m only on wifi… and batter still lasts only for less than a day. even… BT off…

#5

And when you switch off 3G and only use when you really need it? I have noticed that mobile access uses a lot of power when coverage is poor.

#6

yeh… that is true… if no coverage it pushes the processor… so do you mean keeping 4G handles it in better way?

#7

No, 4G has not a higher signal strength than 3G.

I have one of the best solutions to make battery prolonged…
turn off battery saver

Settings → More → Background cleaner → battery Saver (turn off).

It won’t drain battery… just unload apps you don’t want by pressing and holding power button…-> recent tasks… > (and close what you dont’ need)… and leave what you need again and again…

by doing this… My battery is lasting for more than a day!!! :slight_smile:
